Description

Qpid C++ messaging example server.cpp never closes the reply senders. This leaks resources and causes performance issues.

Modifying client.cpp to send the four strings 5000 times give these gross timing results:

protocol	time	server - trunk	server - closes senders
amqp0-10	real	7m 22s	0m 5.9s
amqp0-10	user	2.888s	1.056s
amqp0-10	sys	1.507s	0.661s

Stock or patched server.cpp, amqp1.0, the client program does not finish. It complete 1250 passes of four messages and hangs. Repeated runs all fail on pass 1250. This is probably related to https://issues.apache.org/jira/browse/PROTON-784
